I mean the addon update path for andoid devices.With automatic update function of kodi, the new addon 1.9.13 is not offered to update.

The version 19.13 was only yesterday merged to the main branch at github. It will take time until it is available as a part of kodi helix installation.We have built it for a number of platforms and made available here on forums. Android version is not part of that build yet. We are working on it.
